and the ensuing evaporation of volatileconstituents and hardening of the tube contents.

One object of m invention is the provision of a closure evice which may be employed to replace the usual screw cap but which embodies a closure of such construction that the container outlet may be opened to permit removal of the contents without. completely removing any part of the closure means.

Another object of my invention consists in the provision of a closure structure which is such that it must ride over a high point of resistance into and out of closing position and whi'ch'will, at the same time, effect a sealing closure when it moves into closing position. The closure structure is such that i it is readily applied or removed from the container.

Another feature of my invention consists in the provision of a mouth-piece of nonmetallic material. This mouthpiece is also,

preferably, detachably applied and applicable to standard containers.

Another object of my invention is the provision of an .outlet closure which may be removed from, one container and placed upon another container. I

One embodiment of my invention is illustrated in the accompanying drawings wherein similar characters of reference designate corresponding parts and wherein:

Figure 1 is a fragmentary vertical sectional view through a collapsible dispensing tube showing my novel closing device as applied thereto.

Figure 2 is a vertical sectional view through my novel container closing device showing the closure in different positions with reference to the outlet opening thereof.

Figure 3 is a vertical sectional view showing the arrangement of the extensions whereby the closure device is pivoted to the cap.

Figure 4 is a horizontal sectional taken on line 44 of Figure 3 and Figure 5- 1s a fragmentary perspective view vview showing my invention in association with a collapsible dispensing tube.

In the drawings, one illustrative embodi-r ment of m invention is shown in association with a co lapsible dispensing tube 1 which may be formed with a tapered reduction 2 and an externally threaded discharge neck 3 provided with an opening 4. Obviously,

my invention is not limited to use with a collapsible dispensing tube, because its various features, as hereafter more particular- 1y described, are-broadly applicable to any container wherein a closure of this nature is desired.

The cap 5 which is preferably manu factured from colored bakelite, durez, karo- 11th, or other suitable non-corroding material, may be internally threaded and adapted to engage with the externally threaded discharge neck?) as shown in Figure 1. This cap may be providedwith an,

opening 6 which may be of any desired shape and which is adapted to register with i the opening 4 formed in the discharge neck 3 to form an outlet for the material contamed in tube 1..

For sealing the openingG, I have provided,

a closure device 7 which may be pivoted-to the cap 5 by means of suitable extensions 8. These extensions 8 may be formed with hook portions 9 which engage in oppositely dis posed openings 10 formed in the cap 5 adacent its bottom The inner faces of open- .ings 10 may be beveled to'forma bearing surface 11 for the hook portions 9 of'extensions 8. This prevents them from interfering with the removal or replacement of the cap 5. It will be noted that theopenings 10 are 'efi'ectuall closed against disengagement of the bee sions 8 by the abutment of the bottom of cap 5 against the reduced portion 2 best shown in Figures 1 and 5.

The closure device 7 may be formed with a cup portion 12 which is adapted to contain a yieldable pad 13 of cork or other suitable portions 9 of exteIiof tube 1 as 1 material. This pad 13 is adapted to yield orcompress and flex centrally into the space 14 between it and the top of closure device I 7 when said closure device is oscillated in either direction over the edge orcorner of the 'cap' 5in 't-h'e manner illustrated infull that'a slight contraction, sufiicient. to retain .the closure device 7 opened'or closed position, will occur when said closure device is moved to opened-or closed. position."

. ,Inoperatiomsthe closure device? may be,

oscillated "in either direction by the thumb ofone, hand while thetube 1 is held by the "fingers of-jthesame hand.. The top-of the closure'device may beformed with suitable projections to 'prevent-slippageof the-thumb when opening orclosing the opening 6; The

resiliency ofthe extensions-8, combined with the yieldability of pad 13 and the relatively flattopof cap 5, will be sufiicient to main tain the closure device over opening-6. In other words,.the resiliency of the extensions 8 and pad 13, together with obstruction to material movement which is offered by the edge or corner of cap 5, will hold the said pad against the 'flat top of cap 5 and preventj'accidental opening of the outlet 6.;

From the foregoing description, it w 1l1 be obvious that my invention provides a simple and efl'ectiveclosure which maybe removed.

' from one tube and placed upon another,

which will prevent accidental opening of the outlet, and which will not discolor the tube contents or permithardening of same due to the evaporation of volatileiingredients.

Having thus described my invention,what.

I claim is:

1..As an article of manufacture, a tooth paste container having a ca provided with r a discharge orifice made 0 'a substantially rigid non-corrosive and non-metallic material, and a closurememberadap'ted to be moved over andjaway from said orifice.

2. As an article-of manufacture, a tooth paste container having a cap'provid'ed with a discharge orifice made of a substantially rigid non-corrosive and non-metallic material, and a resilient closure member adapted to be moved over and away from said orifice.

3. The combination of a collapsible dispensing tube having a discharge neck, a nonmetallic apertured cap adapted to engage with said neck, an oscillatable closure device having resilient extensions-pivoted to ture.

said cap and a yieldable pad carried by said closure device for maintaining it in closedposition with reference to said aperture.

4. In combination, a container having -.a discharge neck, an aperturedcap adapted to engage with said neck, a closure device pivoted to said cap by flexible extensions and a yieldable-pad carried by said closure device for assisting said flexible extensions in maintaining it inopened orclosed position with reference to said aperture.

5. The combination. of an apertured sub stantially flat-topped c' 'ap, means pivoted to saidcap by stationary pivots and adapted to be oscillated about such pivots to open and close said "aperture, said 'means embodying resilient parts for maintaining it in contact with the flat'top of said cap.

36. In "combination, a container havlng a discharge neck, a substantially fiat-topped apertured cap adapted. to engage with said neck and anoscillatable closure device having extensions pivoted to said cap and carrying a yieldable pad the resiliency of which .tends 'to hold said closure device in opened or closed position with erture. 1

7. A device of the class described comprising a substantially flat topped apertured cap having means forattaching same to a receptacle, a closure device pivoted to and movable about the said ca'p for, opening and closing said aperture'and a resilient pad carried by said closure. device and expansible against the flat top of said cap for frictionally maintaining said closure device in closed position with relation tosaid aperreference to said ap- 8. A device of the classdescribed com rising a substantially flat-topped aperture cap and a closure device pivoted to said cap .by bow shaped resilient members the resiliency of which holds said closure device against the flat top of said cap and prevents accidental uncovering of said aperture.

9. In combination, a collapsible tube container having a discharge neck provided with an aperture, an oscillatable closure device pivoted to said neck by flexible extensions, and a yieldable pad carried by said closure device for assisting said flexible extensions in maintaining it in open or closed position with reference to said aperture.

In testimony whereof I hereby affix my signature.
